When I was a lot younger I sent Pope John Paul an essay-letter on Biblical support for environmental causes. The Pope sent his blessings, actually.
I guess some basic concepts are lost in the compulsive and sometimes complex rhetoric of political charactes such as Mr. Gore. We all know that people habitually pray for things like recovery from illness and long life. Yet much of society contributes to those things that destroy life and the support mechanisms in place to ensure human survival. So based on their tangible actions people do not care for life but actually would prefer death. So death is what they have. It is all around us - something that we deserve and earned.
I don't know enough about Mr. Gore to comment on him specifically. But in terms of the environmental movement as we know it, I think most (radical)environmentalists spend their time complaining about companies, ranting about how it's wrong to own property and proving that God doesn't exist. If that is all they have to offer to the discussion, we've heard it all before from far better speakers. I think the greatest obstacle the environmental movement are the environmentalists themselves who are detached from the needs and desires of everyday people.
